The answer depends on the shape and what information you have about it.
But basically, it is the sum of the lengths of all line segments that from the boundaries of the shape.
The formula for the perimeter of a square is P equals 4 times a. 'P' represents the perimeter, and 'a' represents a side of the square.
the formula is 1side multiply by 3
Circumference or perimeter = 2*pi*radius or pi*diameter
36x64
Assuming the shape is a regular dodecagon, the formula for calculating the perimeter for a dodecagon of side length n is equal to 12n.
The formula for finding out perimeters of shapes is length+length+height+height=perimeter or what else you can do is (lengthx2)+(heightx2)=PERIMETER
The formula for the perimeter of a square is P equals 4 times a. 'P' represents the perimeter, and 'a' represents a side of the square.
2(length + height)= perimeter
(2) Length + (2) Width = Perimeter
Perimeter of a rhombus = 4 x (length of one side)(Notice how closely the formula resemblesthe one for the perimeter of a square.)
There are many formulas for perimeter depending on what shape you are trying to find the perimeter of. The perimeter is the distance around a shape, so one formula to find perimeter is simply adding all the side lengths together.
Square is a special case of a rectangle and the same formula may be used to find the perimeter
Perimeter = sum of lengths of sides.
Perimeter = sum of the lengths of the sides.
The perimeter of a pentagon is the sum of its 5 sides
no
The formula for the perimeter of a shape depends on the shape. It is the sum of the lengths of all the sides that enclose the shape.
